Named URL patterns have been added to Django recently but the documentation isn’t complete yet.

In urls.py, use url()

urlpatterns = patterns('', 
    url(r'^$', index, name="app_index"),

On the templates, use url()



<a href="{% url app_index %}">Home</a>

On the views, use django.core.urlresolvers.reverse()

from django.core.urlresolvers import reverse
def some_method(request):
  return HttpResponseRedirect(reverse('app_index'))

To export data to CSV, I use CSV::Writer.

def report
  CSV::Writer.generate(output="") do |csv|
    csv << %w(Name Price)
    @items.each do |item|
       csv << [item.name, item.price]
    end
  end

  send_data(output,
    :type => "text/csv",
    :filename => 'report.csv')
  end
end
